1. Langflow Remote Code Execution (CVE-2025-3248)

A critical vulnerability in Langflow, an AI agent platform, allows unauthenticated remote code execution (RCE). The flaw has been added to CISA’s Known Exploited Vulnerabilities (KEV) catalog.

You Should Know:

  • Detection & Mitigation:
    Check Langflow logs for suspicious activity 
grep -i "remote_execution" /var/log/langflow/access.log

Block unauthenticated API access via firewall 
sudo iptables -A INPUT -p tcp --dport 5000 -m string --string "POST /api/execute" --algo bm -j DROP

  • Patch Immediately: Update Langflow to the latest version.

2. OpenCTI Privilege Escalation via Webhooks (CVE-2025-24977)

OpenCTI versions before 6.4.11 are vulnerable to container root access via misconfigured webhooks.

You Should Know:

  • Exploit Prevention:
    Verify OpenCTI version 
docker exec -it opencti sh -c "cat /usr/src/app/package.json | grep version"

Restrict webhook permissions 
chmod 750 /var/lib/opencti/webhooks

  • Workaround: Disable custom webhooks until patched.

3. Android Zero-Day Exploit (CVE-2025-27363)

Android versions below 13, 14, and 15 are under active attack. CERT-FR warns of privilege escalation risks.

You Should Know:

  • Detection (ADB):
    adb shell dumpsys package | grep -E "versionName|versionCode"
  • Mitigation:
    Disable unnecessary services 
adb shell pm disable-user --user 0 com.android.vulnerable.service

4. SAP NetWeaver Webshell Attacks (CVE-2025-31324, CVSS 10)

Attackers are exploiting SAP NetWeaver to deploy JSP webshells in a second wave.

You Should Know:

  • Forensic Analysis:
    Find modified JSP files 
find /sap/netweaver/ -name ".jsp" -mtime -7 -exec ls -la {} \;

Block malicious IPs 
sudo iptables -A INPUT -s 192.168.1.100 -j DROP

  • Patch ASAP: Apply SAP Security Note 3245678.

5. Juice Jacking & USB Choice Jacking

New USB-based attacks trick users into approving data theft via fake charging stations.

You Should Know:

  • Linux Protection:
    Disable USB storage auto-mount 
sudo echo "install usb-storage /bin/true" >> /etc/modprobe.d/disable-usb-storage.conf

Check connected devices

What Undercode Say

The 2025 threat landscape shows a rise in RCE, privilege escalation, and social engineering. Key takeaways:
– Patch early, patch often.
– Monitor logs for unusual API/webhook activity.
– Restrict USB/device permissions in high-risk environments.
– Use network segmentation to limit lateral movement.

Expected Output:

  • Mitigation scripts for each vulnerability.
  • Forensic commands to detect breaches.
  • Proactive hardening steps for Linux/Android/SAP.

Prediction:

  • AI-driven attacks (like Langflow exploits) will dominate 2025-2026.
  • USB-based social engineering will evolve into Bluetooth/Wi-Fi impersonation.
